This directory contains the erlang source modules for an implementation of the ITU-T version of the Signalling Connection Control Part (SCCP). See ITU-T recommendations Q.711-Q.715 for the specification this implementation is derived from. The basic structure of the SCCP appears in Figure 1/Q.714 - SCCP overview. It is divided into four functional blocks (ref: Q.714 clause 1.4): SCCP connection-oriented control (SCOC) SCCP connectionless control (SCLC) SCCP management (SCMG) SCCP routing control (SCRC)
